Raijin was born in Chun-Nan in a very traditional town, living there most of his childhood until his family decided to move for a change of air and a better life. As a kid that had always been shy, this did not sit well with Raijin. The new school was very different from what he was used to, hardly being able to go out of his way to talk to anyone. Until one day a somewhat awkward dragon reached out first. He and Pepper became close friends, then Aqua followed.

Since he was a child, his parents had told him tales of their ancestors, of warriors capable of wielding the lightning itself. He always dismissed it as a fun story to entertain kids. Turns out, it wasn't. His dormant powers awakened during a bad storm. Raijin was already easily startled, his shyness devolved into anxiety over the years. His fear and anxiety combined with a stressful day was all it took to cause a blackout, triggering his own electricity as self-defense mechanism. A distressed call later, his friends rushed there to comfort and help him. They would all figure it out together, they promised. He believed them.

After graduating from high school, Pepper and Aqua brought up the idea of renting an apartment together in a far nicer and better city than their small town. Raijin agreed, and the trio moved fairly quickly, now busy between work, college and keeping their powers from hell from absolutely ruining their lives. They're managing so far.
